Letters Patent .N ...102,801, dated May 1870.

IMPROVEMENT IN GANGSPLW.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known thatI, PETER H. FLAivsBURGH, of Haywards, Alameda county, State of California, have invented certain new and useful Improvements vin Gang-Flows; and l do hereby declare the following description and accompanying drawings are snflcient -to enable any person skilled in t-he art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.

The object of my invention is to provide an improvement in gang-plows, whereby the plows may be easily' and readily raised or depressed, as may be desired, without the necessity of raising and lowering the carriage.

This is accomplished by constructing the frame, composed ot' two beams, one longer than the other, placed at a snliicient distance apart and mounted on wheels. To the rear end, by standards, are attached thc plows,y one to each beam. lhe upper ends of these standards are; notched so as to forni racks, while their lower ends are fastencd,'one'vto each landside, and pass through supports on the sides of the beams. Av toothed segment, operated` bylevers, works each of these racks or standards. Near the wheels is a shaft having two arms or levers, the outside one being the longest, and within convenient 'reach of the driver, and which may vbe held in a rack'in any position. A rod connects the llever which operates the toot-hed segment to the levers in front, so that, when the levers are thrown back, the plows are raised ont of the ground, and, when thrown forward, theyenter it to any desired depth.

A rodextends from hack of the vattachment of the segment, and is fastened loosely to the bottom of the, standard near the land-side, which throws the point of the plow up. Then the levers are thrown back the plows will easily clear themselves from the ground. A hinge may be employed in placev of the racks and pinions, to raise and lower the plows, andl the same end attained.

To more fully illustrate and explain my invention, reference is had vto the accompanying drawings forming a part of this specification, of which- Fignre l lis a side elevation.

Figure 2 is a top view.

Similar letters of reference, in each of the figures, indicate like parts.

A and B are two beams placed at a sncient distance apart, having the pole or tongue C placed between their front ends, the whole being mounted 'on wheels. The beam B is longer thanl the'beam A. Plows D and D' are attached one to each beam near their rear ends, by means of standards E and E', the lower ends of which' are attached t0 the land-side of each plow, while Aone 4side of the upper end is notched so as to form a rack.

segmental piuions F and F', having levers G and G', are attached-so as to operate i`n the rack and raise and lower,.the^plows.

Near the wheels, and within convenient reach of the driver, so as to be operated by.-hand, are two levers, I I, fastened to a shaft, H, working in boxes on the beams. Bars a a connect the top of the. levers, which bp'- erate the 'toothed segments with the levers l I', 'so that, by operating the levers in front, the plows may Abe either raised out of the ground or lowered to any desired depth.

Small rods bb are inserted in the beam, back of theV toothedl segment, and the other ends are fastened so asyto work loosely in the standard near the land-sides, so that, when the levers are thrown forward, the point ot' the plow will be turned up, and thus easily and readily'emerge from the ground.

Having thus described my invention,

What I ola-im, and desire to secure vby Letters Patent, is-

'1. The plows D D in a gang, moved up and down by the standards E E', forming racks, as shown, the

segments F F', the levers G G', or an equivalent device, operating ,substantially as and for the p nrpose Aherein described.

2. -The braces 71.71', attached to the plows Aat one end, and operating to throw the plows out ,of the ground -in raising, substantially as herein described, in

f combination with the lifting device above claimed.

In witness whereof I have hereunto set my hand and seal.
